Fortunately, scouring music libraries for examples is a challenge that Frank has long embraced.

Saturday afternoon, the Concord Women’s Chorus presents its spring concert, “For a Dream’s Sake: Giving Women Voice.” The program showcases “Les Sirènes,” by Lili Boulanger, who in 1913 was the first woman to win the Prix de Rome, as well as music by contemporary composers Abbie Betinis (“Be Like a Bird”), Libby Larsen (“Canticle of Mary”), Eleanor Daley (“Rose Trilogy,” “Child with the Starry Crayon,” and “A Hymn for St. Cecilia”), Beth Denisch (“Facial” and “Oh Strange and Lucid Moment”), and Ruth Watson Henderson (“The Path of Light”).

“Finding credible and beautiful and complex music for women’s voices has always been a challenge,” said Frank, who has headed the 53-year-old Concord Women’s Chorus for the past two decades. “A lot of music for women’s voices is an arrangement of something that was not specifically written for them.

“My personal goal is always to find music, both historical and contemporary, organically written for women’s voices. And since women composers have won the Pulitzer Prize for music in two out of the past four years — Jennifer Higdon in 2010 and Caroline Shaw in 2013— it seemed like the right moment to highlight women composers.”

The Concord Women’s Chorus traveled to Philadelphia this spring to perform the same program.

A special addition to this weekend’s concert will be the participation of the Concord-Carlisle High School girls’ chorus, reflecting the group’s commitment to promoting music in younger singers.

“Just as we have been inspired by the composers who came before us, part of our mission is to inspire the next generation of musicians,” said Kathleen Chapman, chairwoman of the ensemble. “It has been increasingly important to our group to pass the torch on and encourage young singers to love the music we love, particularly pieces by women, which do not get performed nearly as often as those by their male counterparts.”

And the 60 women, who come from Concord and 20 other nearby towns, hope that their very presence teaches the high school singers something about the role of music in an adult’s life as well.

“We want them to see that music can be a lifelong pursuit, not just something you do in middle school or high school,” said Chapman. “Those of us in the Concord Women’s Chorus have continued this throughout our lives simply because we love singing so much.”

The Concord Women’s Chorus, joined by the high school singers and accompanied by Boston pianist Scott Nicholas, performs Saturday at 4 p.m. at Trinity Episcopal Church, 81 Elm St. in Concord. Tickets are $25 for adults, $20 for seniors and students, and $10 for children 12 and under, and can be purchased at www.concordwomenschorus.org. For more information, call 978- 852-4239.
